In the early 1900s, why was there so little settlement on the Great Plains ?
White explorers did not travel into the region until the mid 1800s.
The Battle of Fallen Timbers had driven American settlers from the region.
Conditions there were not suitable for the kind of farming done at that time.
White settlers could not find a route through the Appalachian Mountains.

Texas’ gulf coastal plains are the western extension of the coastal plain extending from the atlantic ocean to beyond the rio grande. its characteristic rolling to hilly surface covered with a heavy growth of pine and hardwoods extends into east texas. in the increasingly arid west, however, its forests become secondary in nature, consisting largely of post oaks and, farther west, prairies and brushlands.
